Mich. Comp. Laws § 89.3
No ordinance or resolution passed by the council shall have any force or effect, if, on the day of its passage, or on the next day thereafter, the mayor, or other officer or person legally discharging the duties of mayor, shall lodge in the office of the clerk a notice, in writing, suspending the immediate operation of such ordinance or resolution.
If the mayor, or other officer or person legally exercising the office of mayor, shall, within 3 days after the passage of any such ordinance or resolution, lodge in the office of the city clerk his reasons in writing, why the same should not go into effect, the same shall not go into effect, nor have any legal operation, unless it shall, at a subsequent meeting of the council, be passed by a 2/3 vote of all the aldermen elect, exclusive of the mayor or other officer or person legally exercising the duties of the office of mayor, and if so repassed shall go into effect according to the terms thereof. If such reasons shall not be lodged with the clerk as above provided, such ordinance or resolution shall have the same operation and effect as if no notice suspending the same had been lodged with the city clerk, and no ordinance or resolution of the council shall go into operation until after the expiration of 24 hours after its passage, unless the said mayor, or acting mayor, shall approve the same in writing.
